In this laptop screen replacement guide, we will show you how to remove white spots from your laptop monitor in an easy way. Here are the following steps for you:
Step 1: Turn off your Toshiba laptop and disconnect its power cord and video cable so that you can remove the laptop keyboard.
Step 2: Place your laptop screen down with its face on the table so that you can gain access to its bottom side.
Step 3: Place some small pieces of cloth (tissues, towels or old clothes, etc.) on the table for your laptop screen to lean against to not damage the screen face.
Step 4: Remove the screws that are used to fix your laptop screen bezel with a screwdriver. After removing the screws, you can take away your laptop screen bezel easily. There is another type of screw that is used for connecting two parts of laptops together. You need to use your plastic pry tool or credit card to separate those two parts.
Step 5: When you open your laptop screen, you will see its cables inside it. Be careful with those cables and detach them carefully. You can find one cable for the inverter or backlight. Three spade connectors are used to connect the motherboard of laptops together. And also, notice the hook-like cable that is used to lock your laptop screen.
Step 6: When you detach all the connectors and cables that link to your laptop LCD’s upper part, you can remove it easily from your computer case by pulling its top side while holding its bottom part.
Step 7: Now, you can check whether a faulty inverter or backlight causes the white spots on the laptop screen. It’s easy to find out, just connect the new inverter or backlight and turn on your laptop screen again. If the white spots are still there, then it’s caused by a faulty LCD screen.
Step 8: Remove excess screws from your old LCD screen with a screwdriver. If you find any spade connectors, make sure to detach them carefully.
Step 9: Put the new LCD screen into your laptop case and insert its connectors first, then attach screws to it. And re-connect all those spade connectors to their original locations.
Step 10: Turn on your Toshiba laptop and enjoy a clear view from your new LCD screen.
